Abstract The energy from renewable sources had always been perceived as free or at least lower cost energy, with its sourcing from natural sources such as solar radiation and wind energy. In actual the cost breakdown of renewable energy would exceed that of traditional energy sources in almost all cases. This study attempts to produce a cost model for renewable energy systems. The model takes into account different requirements and site variations into account. In this paper; elements of cost model Renewable Energy System (RES) especially photo-voltaic solar systems has been investigated. Cost items are presented alongside a to-do checklist for new Photo-Voltaic (PV) solar energy system. The goal of this study is to construct a model that would cover the cost sources as well as bring into attention the unexpected sources of cost variations that includes all possible cost items of new solar renewable energy system. The feasibility of the new system is expressed in terms of Total Cost (T.C) and Cost of Energy (COE). The model can evaluate feasibility of off-grid as well as on-grid systems. The model investigated properly as well as an empirical analysis and verified through results comparison with reviewed case studies. The results revealed that cost of off-grid systems are higher than cost of on-grid systems due to cost of batteries as well as cost of standby generators. So, it would be more feasible to use off-grid system only in remote or isolated area. Risk Cost lists, ranking and successful factors of new renewable project are exhibited.

Providing energy to areas isolated from the electricity grid through the use of a smart integrated renewable energy system (SIRES) is proposed in this study for Valparaiso, Chile. The study analyzes the process of identifying the appropriate size of a SIRES considering technical and economic factors. An optimization model proposed in the literature was modified, and a subsequent spatial–temporal analysis of the different variables was conducted. The model comprises locally available renewable energy resources, such as biomass, biogas, wind power, solar photovoltaic, and thermal power. Furthermore, it was used to determine the energy potential of each of the isolated areas, identifying those areas in which the SIRES could be implemented as a sustainable solution. The design simulates the cost of the initial investment and energy generation in the chosen areas. The study also includes the selection of different system components and the use of the general model to determine the optimal combination of energy subsystems for isolated areas with the aim of minimizing the cost of energy generations. Finally, an economic evaluation showed that the use of a SIRES based mainly on solar energy supported by biomass, biogas, and mini-wind power costs approximately three times less than extending the electricity grid network.

Recently, renewable energy has been in place to cater the depreciation of main energy. The presence of renewable energy sources can be made in hybrid to satisfy the demand in the distribution system. Nevertheless, the growth in number for renewable energy could lead to cost increment. This paper presents the optimization process of Hybrid Renewable Energy System (HRES) using Modified Evolutionary Strategy (ES) technique for cost minimization. The study involves the development of optimization engine for modified ES in order to solve the cost minimization of HRES. The improved version of ES is expected to address the computation burden experienced by the traditional ES technique. Results obtained from the implementation of the modified ES managed to reveal that its implementation is worth in terms of minimizing the cost

Hybrid Renewable Energy

This study focuses on improving the sustainability of electrical supply in the healthcare system in the UK, to contribute to current efforts made towards the 2050 net-zero carbon target. As a case study, we propose a grid-connected hybrid renewable energy system (HRES) for a hospital in the south-east of England. Electrical consumption data were gathered from five wards in the hospital for a period of one year. PV-battery-grid system architecture was selected to ensure practical execution through the installation of PV arrays on the roof of the facility. Selection of the optimal system was conducted through a novel methodology combining multi-objective optimisation and data forecasting. The optimisation was conducted using a genetic algorithm with two objectives (1) minimisation of the levelised cost of energy and (2) CO2 emissions. Advanced data forecasting was used to forecast grid emissions and other cost parameters at two year intervals (2023 and 2025). Several optimisation simulations were carried out using the actual and forecasted parameters to improve decision making. The results show that incorporating forecasted parameters into the optimisation allows to identify the subset of optimal solutions that will become sub-optimal in the future and, therefore, should be avoided. Finally, a framework for choosing the most suitable subset of optimal solutions was presented.

The point of reference of an exceptional design in a system is the lack of a crisis. Electricity is expected to flow effortlessly with the flick of a light switch in a home or industrial setting. The equipment behind the switch – the generators providing the electric source – is meaningless to the end-user. It is designed well and only noticeable in a crisis (blackout as a worst case scenario). However, when the renewable energy technology is incorporated in the present infrastructure, it ought not to create additional problems in the electrical footprints. The cost-effectiveness of the renewable generation must provide substantial eco-friendly benefits to justify the capital expenditures. Only when the renewable energy system is designed well and seamlessly integrated in the grid to minimize the fossil-fuel dependency, the potential crisis will be averted.
